Human IL-37 / IL-1F7 Protein, His Tag

  • Synonym
    IL1F7,IL37,FIL1Z,IL1H4,IL1RP1
  • Source
    Human IL-37, His Tag (ILB-H51H5) is expressed from E.coli cells. It contains AA Lys 27 - Asp 192 (Accession # Q9NZH6-2).
  • Molecular Characterization
    Online(Lys 27 - Asp 192) Q9NZH6-2

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 20.1 kDa. The protein migrates as 20-23 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, 1 mM TCEP, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • Background
    Interleukin-1 family member 7 (IL1F7b) ,a member of the IL-1 family, is aslo known as interleukin-37, interleukin-1 homolog 4 (IL-1H4), interleukin-1 zeta (IL-1 zeta) and interleukin-1-related protein, which can interact with SMAD3 and bind to IL18R1, but not to IL1R1, with lower affinity than IL18. IL1F7b is a suppressor of innate inflammatory and immune responses involved in curbing excessive inflammation. This function requires SMAD3. Therefore,IL1F7b can suppress, or reduce, proinflammatory cytokine production, including IL1A and IL6, as well as CCL12, CSF1, CSF2, CXCL13, IL1B, IL23A and IL1RN, but spare anti-inflammatory cytokines. Furthermore,IL1F7b can also inhibit dendritic cell activation.
